Summary

To test the feasibility of an intervention designed to replace sedentary time with physical activity in older Latinos, delivered in their homes to improve cognitive function and brain connectivity.

Detailed description

After being informed of the study and potential risks, all patients giving informed consent will undergo a focused phone interviews, followed by screening to determine eligibility. Participants that meet inclusion criteria will undergo baseline cognitive function testing via video (following NIH toolbox guidelines for remote cognitive function assessment), followed by a one week measurement of sedentary time using a physical activity monitor (actigraphy). At week 0, participants will be randomized into either a physical activity group to break up sedentary time or activity guidelines only in a 1:1 ratio. Follow up occurs at 6 weeks using the same measures as baseline.

Conditions

• Sedentary Behavior
• Cognitive Impairment

Interventions

Type	Name	Description
BEHAVIORAL	Ecological Momentary Intervention	Participants will wear a Fitbit that has been programmed to deliver a notification (a buzz) when activity has ceased for more than 10 minutes. They will receive suggestions on their Illumivu mEMA smartphone app on how to replace sitting time with PA such as standing up 5 times or taking 20 steps, or even performing a short (20 seconds) preferred dance routine. Fitbit data will be captured in real-time via the iCardia platform. Participants will receive reminders from their smartphones to enter real-time feedback on activity options selected and how successful they were in adopting the option. These data will allow tracking of underlying preferences for behaviors and to tailor the program accordingly.
